Abstract
PURPOSE: We performed biochemical and histopathological evaluations to assess the effects of 2-APB on ischemia-reperfusion induced testicular damage. MATERIALS AND METHODS: A total of 28 rats were randomly divided into 4 groups, including sham treated, ischemia-reperfusion, ischemia-reperfusion plus 2 mg/kg 2-APB and ischemia-reperfusion plus 4 mg/kg 2-APB. Testicular tissue superoxide dismutase, glutathione, malondialdehyde, total antioxidant capacity and DNA fragmentation levels were determined. Testicular tissue samples were examined by histopathology and TUNEL staining. RESULTS: Mean superoxide dismutase, total antioxidant capacity and glutathione were significantly higher in the sham treated group than in the ischemia-perfusion group (p <0.05). Mean malondialdehyde and DNA fragmentation levels were significantly lower in the sham treated group than in the ischemia-reperfusion group (p <0.05). After 2-APB treatment superoxide dismutase, total antioxidant capacity and glutathione were significantly increased but malondialdehyde and DNA fragmentation levels were significantly decreased compared to the ischemia-reperfusion group (p <0.05). The number of TUNEL positive cells was significantly lower in the 2-APB treatment groups than in the ischemia-reperfusion group (p <0.05). CONCLUSIONS: In rats 2-APB reduced the oxidative stress and apoptosis caused by testicular ischemia-reperfusion injury. The testicular protective effect of 2-APB appears to be mediated through its antiapoptotic and antioxidative effects.
